Coils and assembly from a single source


Due to the degree of filling, only alpha coils with start and end wire on the outer diameter were considered.
Due to the degree of filling, only alpha coils with start and end wire on the outer diameter were considered.

INTEGRA Biosciences is a good example of a laboratory technology company that obtains customer-specific coils and PCB assembly from KUK from a single source. Recently, INTEGRA received valuable support in coil production for a sophisticated laboratory device for pipetting.

INTEGRA Biosciences ist ein gutes Beispiel für ein Labortechnik-Unternehmen, das von KUK kundenspezifischen Spulen und Leiterplattenbestückung aus einer Hand bezieht. Zuletzt erhielt INTEGRA wertvolle Unterstützung bei der Spulenproduktion für ein anspruchsvolles Laborgerät zur Pipettierung.

KUK has been assembling PCBs for INTEGRA for several years, a service that is particularly appreciated by customers in the region of KUK's Swiss headquarters. Now the cooperation has been further extended by KUK also being involved in the further development of the liquid handling products. For this purpose, a customer-specific motor design was tackled with very tough requirements, not only in terms of performance:

On the one hand, the installation space should be kept as small as possible, on the other hand, the windings must also be very precisely designed. You can't get a motor like this off the shelf.

Samples of custom coils delivered quickly

On-site visits and the first samples, which were delivered very quickly, showed that KUK is the most competent partner for this project in terms of coil manufacturing. In the further development phases up to series production, the technical milestones were achieved in a short time. Project buyer Sabrina Hug also appreciates the advantages of INTEGRA being able to procure winding goods and PCB assembly from one and the same supplier.  

As a high-tech company, INTEGRA Biosciences was able to define the requirements very clearly. Due to the degree of filling, only alpha coils with start and end wire on the outer diameter were considered. Energy efficiency is a key issue with the battery-powered handheld device, as lower energy consumption pays off 1:1 through longer operating time.

We appreciated KUK's support after the initial design proposal. The open approach allowed us to make some improvements to the coil and simplify the manufacturing process.

Assembly steps precisely matched to customer requirements

In terms of assembly, this laboratory technology project is also a good example of KUK's flexibility as a contract manufacturer: in addition to coil winding, further assembly steps are carried out - precisely tailored to the customer's needs. Thus, together with INTEGRA, it was possible to work out a customised manufacturing process that divides the value-added steps according to the customer's wishes between KUK and the laboratory technology company:

Needless to say, a seamless transition to the assembly line at INTEGRA is ensured. In addition, different coloured wires help to better distinguish between the individual coil outlets in order to minimise the risk of errors.

Andreas Wild, Head of Product Management KUK Group


This innovative project is thus a good example of how cooperation between coil suppliers and laboratory technology companies can reduce production time and increase the quality and reliability of the coils. Last but not least, it was also about improving the working methods of the laboratory staff.

Insulation layer on magnet wires: A common stumbling block for engineers

In coil production, the insulation of the wire has an influence on a wide variety of product properties such as application range, service life, costs or coil design. Wire insulation also has an effect on various factors during coil manufacturing, such as scrap or further processing. This article summarises the essential facts about wire insulation - and its effect on coil design - for engineers.

What material can coils be wound from?

In coil production, the wire used plays a central role. While copper is undoubtedly the most commonly used conductor material, especially for customer-specific coil projects, it is also worthwhile to test alternative coil wire, depending on the application.

What is the advantage of orthocyclic windings?

Orthocyclic coils are characterised by a high copper fill factor (often approx. 70%), so that a comparatively high magnetic field is realised in the smallest possible space.

Self-supported coils: Facts about coils made of selfbonding wire

Self-supported coils are coils made of wire that is coated with a thermoplastic layer - the bonding varnish. The term selfbonding enamel wire already indicates it: This wire is bonded during the winding process to give the coil the necessary stability without any other aids, especially in the case of air coils. The use of selfbonding wire can offer advantages over a bobbin coil in some cases, ...

What is the purpose of edgewise winding?

Edgewise winding is one of the modern trends in coil manufacturing. The principle of this winding technology is that the rectangular section wire is wound not on the flat part of the wire but on the short side of the wire. That’s where the terms edgewise winding or side-winding stands for.

Misconceptions about the fill factor of electric coils

In the realm of electric coils, there exists a common misconception among engineers regarding the fill factor. This misconception often leads to misunderstandings about the overall efficiency and performance of these coils. It is imperative to address these misconceptions and shed light on the true implications of the fill factor.
